The beta became the product but the problem is still there.
I was not able to rename a tag or delete an unused tag in the new version. I could not do it in Windows, or Android or web versions. My windows desktop evernote version was:
v 10.3.7 build 2018 public
Editor: v111.0.14414
Service: v1.22.6
I found a workaround: I installed a legacy version. I was able to delete and rename tags in it and I was able to use both, legacy and the latest version at the same time.
